Performance analysis of ATM in wireless environments

by Wang, Yi

Abstract (Summary)

ATM networks usually run in environments with very little erron, such as optical fibers.
The popularity of ATM has started to extend to harsh error environments, for example,
the wireless environments. To be able to achieve reliable data transfer in ATM networks
in hash error environments, new protocol design is needed. In addition to the physical
channel errors, ce11 loss due to ATM congestion is another factor that affects the
performance of the ATM network. Research in the past several years was focused on
combathg the physical chamel errors only. However, little work has ken done to address
the problern of the ceIl loss due to ATM congestion.
In this thesis work. two enor control architecturesare proposed to address both the
physical chamel errors and the ce11 loss due to ATM congestion. A computer simulation
mode1 is implemented. The simulation results based on a cellular channel and a satellite
channel are collected and analyzed.
